Precautions for SafetyThe manufacturer shall not assume any liability for the damage caused by not observing the description of this manual.

DANGER

Turn off breaker.

Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breaker for both the indoor and outdoor units to the OFF position. Otherwise, electric shocks may result.

Before opening the intake grille of the indoor unit or service panel of the outdoor unit, set the circuit breaker to the OFF position.Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with the interior parts.Only a qualified installer (*1) or qualified service person (*1) is allowed to remove the intake grille of the indoor unit or service panel of the outdoor unit and do the work required.

Before starting to repair the outdoor unit fan or fan guard, be absolutely sure to set the circuit breaker to the OFF position, and place a “Work in progress” sign on the circuit breaker.

When cleaning the filter or other parts of the indoor unit, set the circuit breaker to OFF without fail, and place a “Work in progress” sign near the circuit breaker before proceeding with the work.

When you have noticed that some kind of trouble (such as when an error display has appeared, there is a smell of burning, abnormal sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the air conditioner, do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a qualified service person. Take steps to ensure that the power will not be turned on (by marking “out of service” near the circuit breaker, for instance) until qualified service person arrives. Continuing to use the air conditioner in the trouble status may cause mechanical problems to escalate or result in electric shocks or other failure.

Electric shock hazard

When you access inside of the service panel to repair electric parts, wait for about five minutes after turning off the breaker. Do not start repairing immediately.Otherwise you may get electric shock by touching terminals of high-voltage capacitors. Natural discharge of the capacitor takes about five minutes.

Prohibition

Place a “Work in progress” sign near the circuit breaker while the installation, maintenance, repair or removal work is being carried out.There is a danger of electric shocks if the circuit breaker is set to ON by mistake.

Before operating the air conditioner after having completed the work, check that the electrical parts box cover of the indoor unit and service panel of the outdoor unit are closed, and set the circuit breaker to the ON position. You may receive an electric shock if the power is turned on without first conducting these checks.

Stay on protection

If, in the course of carrying out repairs, it becomes absolutely necessary to check out the electrical parts with the electrical parts box cover of one or more of the indoor units and the service panel of the outdoor unit removed in order to find out exactly where the trouble lies, wear insulated heat-resistant gloves, insulated boots and insulated work overalls, and take care to avoid touching any live parts.You may receive an electric shock if you fail to heed this warning. Only qualified service person (*1) is allowed to do this kind of work.

When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because the oil that coats the pipes may otherwise burn.When repairing the refrigerating cycle, take the following measures.1) Be attentive to fire around the cycle. When using a gas stove, etc., be sure to put out fire before work;

otherwise the oil mixed with refrigerant gas may catch fire.2) Do not use a welder in the closed room. When using it without ventilation, carbon monoxide poisoning may

be caused.3) Do not bring inflammables close to the refrigerant cycle, otherwise fire of the welder may catch the

inflammables.

Refrigerant

The refrigerant used by this air conditioner is the R410A.

Check the used refrigerant name and use tools and materials of the parts which match with it.For the products which use R410A refrigerant, the refrigerant name is indicated at a position on the outdoor unit where is easy to see. To prevent miss-charging, the route of the service port is changed from one of the former R22.

For an air conditioner which uses R410A, never use other refrigerant than R410A. For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating cycle and an injury due to breakage may be caused.

When the air conditioner has been installed or relocated, follow the instructions in the Installation Manual and purge the air completely so that no gases other than the refrigerant will be mixed in the refrigerating cycle. Failure to purge the air completely may cause the air conditioner to malfunction.

Do not charge refrigerant additionally. If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the refrigerating cycle changes resulted in change of air conditioner characteristics or refrigerant over the specified standard amount is charged and an abnormal high pressure is applied to the inside of the refrigerating cycle resulted in cause of breakage or injury. Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute vacuuming, and then newly recharge the specified amount of liquid refrigerant.In this time, never charge the refrigerant over the specified amount.

When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other than R410A into the specified refrigerant. If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating cycle resulted in cause of injury due to breakage.

After installation work, check the refrigerant gas does not leak. If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.

Never recover the refrigerant into the outdoor unit. When the equipment is moved or repaired, be sure to recover the refrigerant with recovering device.The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as breakage or injury is caused.

Assembly / Wiring

After repair work, surely assemble the disassembled parts, and connect and lead the removed wires as before.Perform the work so that the cabinet or panel does not catch the inner wires.If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or fire is caused at user’s side.

Insulator check

After the work has finished, be sure to use an insulation tester set (500 V Megger) to check the resistance is 1 MΩ or more between the charge section and the non-charge metal section (Earth position).If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.

Ventilation

When the refrigerant gas leaks during work, execute ventilation.If the refrigerant gas touches to a fire, poisonous gas generates. A case of leakage of the refrigerant and the closed room full with gas is dangerous because a shortage of oxygen occurs. Be sure to execute ventilation.

Compulsion

When the refrigerant gas leaks, find up the leaked position and repair it surely.If the leaked position cannot be found up and the repair work is interrupted, pump-down and tighten the service valve, otherwise the refrigerant gas may leak into the room.The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.When installing equipment which includes a large amount of charged refrigerant such as a multi air conditioner in a sub-room, it is necessary that the density does not the limit even if the refrigerant leaks.If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.

Tighten the flare nut with a torque wrench in the specified manner.Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant leakage.

Nitrogen gas must be used for the airtight test.

The charge hose must be connected in such a way that it is not slack.

For the installation / moving / reinstallation work, follow to the Installation Manual.If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or fire is caused.

Check after repair

Once the repair work has been completed, check for refrigerant leaks, and check the insulation resistance and water drainage.Then perform a trial run to check that the air conditioner is running properly.

After repair work has finished, check there is no trouble. If check is not executed, a fire, electric shock or injury may be caused. For a check, turn off the power breaker.

After repair work (installation of front panel and cabinet) has finished, execute a test run to check there is no generation of smoke or abnormal sound.If check is not executed, a fire or an electric shock is caused. Before test run, install the front panel and cabinet.

Be sure to fix the screws back which have been removed for installation or other purposes.

Do not operate the unit with the valve closed.

Check the following matters before a test run after repairing piping.• Connect the pipes surely and there is no leak of refrigerant.• The valve is opened.Running the compressor under condition that the valve closes causes an abnormal high pressure resulted in damage of the parts of the compressor and etc. and moreover if there is leak of refrigerant at connecting section of pipes, the air is sucked and causes further abnormal high pressure resulted in burst or injury.

Check after reinstallation

Only a qualified installer (*1) or qualified service person (*1) is allowed to relocate the air conditioner. It is dangerous for the air conditioner to be relocated by an unqualified individual since a fire, electric shocks, injury, water leakage, noise and / or vibration may result.

Check the following items after reinstallation.1) The earth wire is correctly connected.2) The power cord is not caught in the product.3) There is no inclination or unsteadiness and the installation is stable.If check is not executed, a fire, an electric shock or an injury is caused.

When carrying out the pump-down work shut down the compressor before disconnecting the refrigerant pipe.Disconnecting the refrigerant pipe with the service valve left open and the compressor still operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in reputing, injury, etc.

Cooling check

When the service panel of the outdoor unit is to be opened in order for the compressor or the area around this part to be repaired immediately after the air conditioner has been shut down, set the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the service panel.If you fail to heed this warning, you will run the risk of burning yourself because the compressor pipes and other parts will be very hot to the touch. In addition, before proceeding with the repair work, wear the kind of insulated heat-resistant gloves designed to protect electricians.

Take care not to get burned by compressor pipes or other parts when checking the cooling cycle while running the unit as they get heated while running. Be sure to put on gloves providing protection for electric shock and heat.

When the service panel of the outdoor unit is to be opened in order for the fan motor, reactor, inverter or the areas around these parts to be repaired immediately after the air conditioner has been shut down, set the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the service panel.If you fail to heed this warning, you will run the risk of burning yourself because the fan motor, reactor, inverter heat sink and other parts will be very hot to the touch.In addition, before proceeding with the repair work, wear the kind of insulated heat-resistant gloves designed to protect electricians.

Explanations given to userIf you have discovered that the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to the OFF position, and contact a qualified service person to have the repairs done.Do not set the circuit breaker to the ON position until the repairs are completed.

Relocation• Only a qualified installer (*1) or qualified service person (*1) is allowed to relocate the air conditioner.

It is dangerous for the air conditioner to be relocated by an unqualified individual since a fire, electric shocks, injury, water leakage, noise and / or vibration may result.

• When carrying out the pump-down work shut down the compressor before disconnecting the refrigerant pipe.Disconnecting the refrigerant pipe with the service valve left open and the compressor still operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in reputing, injury, etc.

(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person”

Installation

Only a qualified installer (*1) or qualified service person (*1) is allowed to install the air conditioner. If the air conditioner is installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and / or vibration may result.

Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions to install the air conditioner.

Be sure to use the company-specified products for the separately purchased parts. Use of non-specified products may result in fire, electric shock, water leakage or other failure. Have the installation performed by a qualified installer.

Do not supply power from the power terminal block equipped on the outdoor unit to another outdoor unit. Capacity overflow may occur on the terminal block and may result in fire.

Do not install the air conditioner in a location that may be subject to a risk of expire to a combustible gas.If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.

Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure themselves or receive electric shocks if they poke their fingers or other objects into the indoor unit while the air conditioner is running.

Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the local regulations and laws.

Install the circuit breaker where it can be easily accessed by the qualified service person (*1).

If you install the unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement the measures. Accumulation of highly concentrated refrigerant may cause an oxygen deficiency accident.

Do not place any combustion appliance in a place where it is directly exposed to the wind of air conditioner, otherwise it may cause imperfect combustion.

6 Troubleshooting6-1. Overview(1) Before engaging in troubleshooting

(a) Applicable modelsAll Super Module Multi (SMMS, SHRM, Mini-SMMS, SMMS-i) models.(Indoor units: MMO-APOOO, Outdoor units: MMY-MAPOOOO∗, MCY-MAPOOOHT∗)

(b) Tools and measuring devices required• Screwdrivers (Philips, flat head), spanners, long-nose pliers, nipper, pin to push reset switch, etc.• Multimeter, thermometer, pressure gauge, etc.

(c) Things to check prior to troubleshooting (behaviors listed below are normal)

(2) Troubleshooting procedureWhen a fault occurs, proceed with troubleshooting in accordance with the procedure shown below.

NOTERather than a genuine fault (see the List of Check Codes below), the problem could have been caused by a microprocessor malfunction attributable to a poor quality of the power source or an external noise. Check for possible noise sources, and shield the remote controller wiring and signal wires as necessary.

NO. Behavior Possible cause

1

A compressor would not start • Could it just be the 3-minute delay period (3 minutes after compressor shutdown)?

• Could it just be the air conditioner having gone thermo OFF?• Could it just be the air conditioner operating in fan mode or put on the timer?• Could it just be the system going through initial communication?

2 An indoor fan would not start • Could it just be cold air discharge prevention control, which is part of heating?

3An outdoor fan would not start or would change speed for no reason

• Could it just be cooling operation under low outside temperature conditions?

• Could it just be defrosting operation?

4 An indoor fan would not stop • Could it just be the elimination of residual heat being performed as part of the air conditioner shutdown process after heating operation?

5 The air conditioner would not respond to a start / stop command from a remote controller

• Could it just be the air conditioner operation under external or remote controller?

Investigate check code displayed on interface P.C. board of header unit

7 P.C. Board Exchange Procedures

Indoor unit

7-1. Replacement of indoor P.C. boards

Points to note when replacing indoor P.C. board assemblyThe electrically erasable programmable read-only memory (hereinafter EEPROM, IC10) mounted on an indoor P.C. board holds important setting data, including the type and capacity codes intrinsic to the model (set at the factory), as well as the line / indoor / group addresses, high ceiling adjustment setting and the like (during installation, either automatically or manually). Proceed with the replacement of an indoor P.C. board assembly in accordance with the procedure described below.After completion of the work, check the settings again, including the indoor unit No. and group header / follower designation, and confirm the integrity of the refrigerating cycle by conducting a test operation, etc.

<Replacement procedure>

Method 1If it is possible to turn on the indoor unit and read the setting data from the P.C. board to be replaced via a wired remote controller -

Reading EEPROM data: Procedure 1

Replacing P.C. board and turning on power: Procedure 2

Writing EEPROM data in new EEPROM: Procedure 3

Method 2If it is not possible to turn on the indoor unit or read the setting data from the P.C. board to be replaced via a wired remote controller or operate the remote controller due to the failure of its power supply circuit -

Replacing EEPROM (IC10) (For the location of this component and the method to replace it, see the “ EEPROM location diagram” section.)• The EEPROM on the P.C. board to be replaced needs to be removed and mounted on the service P.C. board.


Reading EEPROM data: Procedure 1• If data cannot be read, go to Method 3.

Replacing EEPROM (IC10) again (For the location of this component and the method to replace it, see the “ EEPROM location diagram” section.)• The old EEPROM, supplied with the P.C. board to be replaced and now mounted on the service P.C. board,

needs to be replaced with the new EEPROM, supplied with the service P.C. board.


Writing EEPROM data in new EEPROM: Procedure 3


Method 3If it is not possible to read the setting data due to the failure of the EEPROM itself -Replacing P.C. board and turning on power: Procedure 2

Procedure 2: replacing P.C. board1 Replace the faulty P.C. board with a service P.C. board.

Be sure to replicate the old jumper setting (removal), switch setting (SW501), and connector short-circuit setting (e.g. CN34) on the service P.C. board. (See the diagram at below.)

2 It is necessary to establish a one-to-one correspondence between the indoor unit being serviced and the remote controller.Turn on the indoor unit using one of the methods described below according to the system configuration.

(1) Single (stand-alone) operationTurn on the indoor unit and proceed to Procedure 3.

(2) Group operationA) If it is possible to selectively turn on the indoor unit being serviced

Turn on the indoor unit being serviced and proceed to Procedure 3.B) If it is not possible to selectively turn on the indoor unit being serviced (Case 1)

a) Temporarily disconnect the group control wiring from terminals A and B of the indoor unit being serviced.b) Connect the remote controller wiring to the terminals, turn on the indoor unit, and proceed to Procedure 3.* If this method cannot be used, proceed to the alternative method described below (Case 2).

C) If it is not possible to selectively turn on the indoor unit being serviced (Case 2)a) Remove the CN41 connectors of all other indoor units in the same group.b) Turn on the indoor unit and proceed to Procedure 3.

* Be sure to restore the temporarily removed group control wiring and CN41 connectors to their initial states after Procedure 3 has been completed.

If a short-circuiting plug had been used on the replaced P.C. board, reuse it on the service P.C. board.

If a short-circuiting plug had been used on the replaced P.C. board, reuse it on the service P.C. board.

Procedure 3: writing setting data in EEPROM(The EEPROM of the service P.C. board has been set to the factory default values.)

1 Push the + + buttons simultaneously and hold for at least 4 seconds. (This number corresponds to the same number shown on the Remote Controller Operation Diagram.)(Under UNIT No., ALL is displayed.)At the same time, the CODE No. (DN code) 10 is displayed, and the fan of the indoor unit comes on, with the louver swinging, depending on the model.

2 Push the left part of the button to display the indoor unit No. one by one in the group control. Specify the indoor unit No. whose service PC board was replaced.(This operation is not available if the UNIT No. shows

.)

3 The button allows you to moved the CODE No. (DN code) up / down by one place.

4 First, set the type and capacity codes of the indoor unit.(Changing the type and capacity codes in EEPROM overwrites the factory default settings.)

(1) Set the CODE No. (DN code) to 10 (no change)(2) Use the button to select the type.

(For example, 0001 is for the 4-way cassette type.) - See the CODE No. list.(3) Push the button. (The display should change from flashing to steady.)(4) Use the button to set the CODE No. (DN code) to 11.(5) Use the button to set the capacity code.

(For example, 0012 is for the 027 type.) - See the CODE No. list.(6) Push the button. (The display should change from flashing to steady.)(7) Push the button to bring the system back to normal off state.

5 Next, write any setting changes made on-site after installation, such as address settings, in the EEPROM. Perform the tasks specified in step 1 again.

6 Use the button to set the CODE No. (DN code) to 01 (To set filter sign lighting time)

7 Check the value displayed with the value jotted down in Procedure 1 and information proved by the customer.

(1) If there is a discrepancy, change the setting in accordance with the jotted-down value, and push the button. (The display should change from flashing to steady.)

(2) If there is no discrepancy, do nothing.

8 Use the button to change the CODE No. (DN code).Again, check the value, and change the setting if necessary.

9 Repeat steps 6 and 7 until all the settings are checked.

10 When finished, push the button to bring the system back to normal off state.In the case of group operation, turn the unit off, reconnect the indoor-indoor group control wiring and CN41 connectors, and turn on all the indoor units.(It takes the system about 1 minute to become responsive to remote controller operation.)

* CODE No. (DN code) go from 01 to FF with a few gaps along the way.If you realize you have wrongly corrected a certain setting after pushing the button, you can recover the initial value by pushing the button, provided that the CODE No. (DN code) is yet to be changed.

WARNINGS ON REFRIGERANT LEAKAGECheck of Concentration LimitThe room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space, individual control, energy conservation by curtailing heat and carrying power etc.Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur).In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device.The concentration is as given below.

The concentration limit of R410A which is used in multi air conditioners is 0.3 kg/m3.

NOTE 1 :If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as charged in each independent device.

For the amount of charge in this example:The possible amount of leaked refrigerant gas in rooms A, B and C is 10 kg.The possible amount of leaked refrigerant gas in rooms D, E and F is 15 kg.

NOTE 2 :The standards for minimum room volume are as follows.(1) No partition (shaded portion)

(2) When there is an effective opening with the adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15 % or larger than the respective floor spaces at the top or bottom of the door).

(3) If an indoor unit is installed in each partitioned room and the refrigerant piping is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

NOTE 3 :The minimum indoor floor area compared with the amount of refrigerant is roughly as follows:(When the ceiling is 2.7 m high)
